Insertion or impaction of foreign objects into the tooth pulp chamber or canals by children are common findings, as they often have habit of inserting foreign objects in the oral cavity, but insertion of tooth pick is a rare finding. These foreign objects can become a potent source of infection. Retrieval of these objects from teeth is a challenging aspect of pediatric dentistry. Radiopaque foreign objects can be diagnosed in routine radiographs, which play important role in analysis of the size, location and type of foreign object, however this does not apply for radiolucent objects. The present paper describes a rare case of insertion of tooth pick into the deciduous mandibular molar tooth.
